Abstract

calibração de atraso de grupo de hardware de dispositivo de referência. trata-se de uma localização de um ue de referência que é obtida (por exemplo, de forma iterativa). uma primeira medição de rtt diferencial é determinada com base em rtts entre um ue de destino e cada um dentre o primeiro e segundo nós sem fio, e uma segunda medição de rtt diferencial é determinada com base em rtts entre um ue de referência e cada um dentre o primeiro e segundo nós sem fio. uma estimativa de posicionamento do ue de destino é determinada com base na primeira e segunda medições de rtt diferencial e na localização de ue de referência obtido (por exemplo, uma das localizações de ue de referência obtidas de forma iterativa mais recentes). em outro aspecto, um ue de referência primário dentre uma pluralidade de ues de referência é selecionado, e sua localização é obtida (por exemplo, de forma iterativa). uma localização de outro(s) ue(s) de referência é determinada com base, pelo menos em parte, na localização de ue de referência primário obtida (por exemplo, uma das localizações de ue de referência primário obtidas de forma iterativa mais recentes).reference device hardware group delay calibration. it is a location of a reference ue that is obtained (e.g. iteratively). a first differential RTT measurement is determined based on rtts between a target UE and each of the first and second wireless nodes, and a second differential RTT measurement is determined based on rtts between a reference UE and each between the first and second wireless nodes. a positioning estimate of the target ue is determined based on the first and second differential RTT measurements and the obtained reference ue location (e.g., one of the most recent iteratively obtained reference ue locations). In another aspect, a primary reference ue from among a plurality of reference ues is selected, and its location is obtained (e.g., iteratively). a location of other reference ue(s) is determined based, at least in part, on the obtained primary reference ue location (e.g., one of the most recent iteratively obtained primary reference ue locations) .
